221455A221508A Modutrol IV Resistor Boards
221508A Modutrol IV Resistor Boards are used to controlling up to six Series 90s in parallel with a 135ohm pot or slide wire type series 90 control
Overview

The 221508A Resistor Board can be confi gured to provide the functions of the 4074BYK, 4074EAU, 4074EDC, or 4074EEDresistor kits for Series 90 Modutrol IV motors. For 4074BYK applications, it can allow a single controller to operate up to sixModutrol IV M91XX motors in unison. For 4074EAU application, it adapts an M91XX motor to operate from a 4-20 mAcontroller. In 4074EED applications, it permits operation of up to four M91XX motors from a 4-20 mA signal. The Resistor Boardmounts inside the motor’s wiring box and provides screw terminals for fi eld wiring.
